Expression expected.ts(1109)

by

The error message “expression expected.ts(1109)” indicates that there is a missing or incorrect expression in the code at line 1109. In TypeScript, every statement should be followed by an expression.

To fix this error, you need to make sure that a valid expression is provided at line 1109. This can be a variable assignment, a function call, an arithmetic operation, or any other valid JavaScript expression.

Here’s an example to illustrate the issue and its solution: 


    // Incorrect code with missing expression
    let x: number;
    if (true) {
      x = 5;
      // Missing expression at this line
    }

    // Corrected code with valid expression
    let x: number;
    if (true) {
      x = 5;
      console.log(x);
    }

In the example, the incorrect code is missing an expression after the assignment of the variable “x”. This results in the “expression expected.ts(1109)” error. The corrected code adds a valid expression (a call to console.log) after the assignment, resolving the error.
